I am a Software Engineer with ~2 years of experience specializing in backend development and system architecture.

My focus has shifted from building features to designing systems. I build production-grade backends with a heavy emphasis on correctness (ACID), observability, and scalability. Currently, I am expanding my expertise into the Java ecosystem and Cloud-Native infrastructure (Kubernetes, Observability).
